Comment 65 for bug 877438

I notice several bugs reporting similar problems with older nvidia cards: 877438 (8xxx cards), 940742 (6xxx cards), 943643 (9800), 958251 (8600), 962191 (7100). The problems include generally degraded performance, fuzzy fonts, and/or lagging in games, which did not exist in earlier versions of the nvidia driver.

We've recently added a new 295-33 version of -nvidia to Ubuntu. The changelog doesn't specifically list a fix for this type of problem, but it does list a few performance fixes, and would be worth re-testing. Update to nvidia 295.33 and report back here whether or not it improved the performance.

Note, you might be seeing crashes, corruption, or other assorted problems, but these may be separate bugs, let's just focus on the performance regression on this bug report.
